The DAX slipped at the end of the week as the so-called witches’ sabbath of derivatives expiries knocked the index off an otherwise firm track, with Rheinmetall leading the retreat and underscoring how vulnerable Germany’s market remains once the defense trade loses momentum.
DAX slips as Rheinmetall falls on expiry day
That matters because the DAX has been leaning heavily on a narrow group of winners, especially defense names tied to Europe’s rearmament drive. When a heavyweight like Rheinmetall weakens, it can quickly drag on the benchmark even if the broader macro backdrop has not materially worsened.
Rheinmetall fell to 1,011.8 euros on Friday from 1,016.2 euros the previous session, after a sharp run-up earlier in the year left the stock exposed to profit-taking and technical pressure. The shares are now well below their 50-day moving average of about 1,088 euros and far under the 200-day average of roughly 1,364 euros, while RSI readings around 27 point to an oversold market.
The stock’s slide matters beyond one name. Rheinmetall has become a market proxy for Europe’s defense spending cycle, and any pause in its advance tends to reverberate across German equities because it strips away one of the DAX’s most reliable sources of relative strength.
The move also comes as investors remain alert to geopolitics and defense budgeting, both of which have kept the sector in focus this year. Even after a strong multi-month rally, the market is signaling that the easy gains may be behind the defense trade for now, especially into a volatile options-expiry session.
For investors, the immediate question is whether the pullback is just expiry-driven noise or the start of a deeper reset in one of Germany’s most important market themes. The next catalysts are any fresh signals on European defense orders, broader risk sentiment and whether the DAX can regain momentum without Rheinmetall doing the heavy lifting.
